Tree Pruning in Swansea And All Of South Wales
Tree pruning may be necessary to maintain a tree in a safe condition, to remove dead branches, to promote growth, to regulate size and shape or to improve the quality of flowers, fruit or timber.
Improper pruning can lead to trees becoming unsightly, diseased and/or potentially dangerous. South Wales Tree Services Ltd can carry out all tree pruning services including the three main options below.
Crown reduction is the reduction in height and/or spread of the crown (the foliage bearing portions) of trees. Crown reduction may be used to activate mechanical stress on individual branches or the whole tree, make the tree more suited to its immediate environment or to reduce the effects of shading and light loss, etc. The final result should retain the main framework of the crown, and so a significant proportion of the leaf bearing structure, leaving a similar, although smaller outline. Crown reduction cuts should be as small as possible and in general not exceed 100mm diameter unless there is an over-riding need to do so.
Crown lifting is the removal of the lowest branches and/or preparing of lower branches for future removal, usually for traffic clearance or to ensure people's safety. Good practice dictates crown lifting should not normally include the removal of large branches growing directly from the trunk as this can cause large wounds which can become extensively decayed. This can lead to long term problems or more short-term biomechanical instability. Crown lifting on older, mature trees should be avoided or restricted to secondary branches or shortening of primary branches rather than the whole removal wherever possible. Crown lifting is an effective method of increasing light transmission to areas closer to the tree or to enable access under the crown but should be restricted to less than 15% of the live crown height and leave the crown at least two thirds of the total height of the tree.
Crown thinning is the removal of a portion of smaller/tertiary branches, usually at the outer crown, to produce a uniform density of foliage around an evenly spaced branch structure. It is usually confined to broad-leaved species. Crown thinning does not alter the overall size or shape of the tree. Material should be removed systematically throughout the tree, should not exceed the stated percentage and not more than 30% overall. Common reasons for crown thinning are to allow more light to pass through the tree, reduce wind resistance, reduce weight (but this does not necessarily reduce leverage on the structure) and is rarely a once only operation, particularly on species that are known to produce large amounts of epicormic growth.
